Now I mostly worry about Linux and FreeBSD. |Admittedly, some really old versions. Sure. Oh the compatibility of shells i meant, of course. But that mostly colours, now that ~/.profile ensures HOSTNAME and LOGNAME per se. No more \XY escapes here, except \e and the \[..\] that some need (to get it column counting right, with colours) (SHTYPE=bash and =yash). And the "set -o" you need/can to get where you want to be, ksh for example braceexpand, emacs-usemeta (if possible), expand_aliases (bash), cdprint/emacs/tabcomplete (NetBSD ksh). It is of course all a bitrot-affine compatibility mess. You look for $0, sometimes deeper for some *_VERSION, for $OSTYPE (which my ~/.profile sets, too). But in the end it is all a mess. If i recall correctly i once proposed a standardized VERSION or xy thing so that one could easily identify, even in subshells. But that would affect future shells only, anyhow. At one time i have thrown away a lot of tests, since fish and some other shells i will never use no more, what remains is just enough to start working the best i can with dash, bash, ksh. Last change on PS1 in March 2018, i usually only have one account per $HOSTNAME. Pretty bitter is shells without aliases, where the a-lia-ses have to be created as sh_ell_functions. And then one says builtin, the other says built-in. Yeah i mean computing would be nice, if there would not be those uncountable quirks you need in real life. The maintainer of libinput has written a short down-to-earth article on that a few years ago. That reminds me of my bitter gut feeling that something bad will happen, all these days, but luckily the rocket that carried some real penis lifted successfully. --steffen | |Der Kragenbaer, The moon bear, |der holt sich munter he cheerfully and one by one |einen nach dem anderen runter wa.ks himself off |(By Robert Gernhardt)

The backup directory isn't for paranoia, actually. It's so the first time that I install my custom dotfiles on a particular machine, if there is a prexisting dot-file, say, .profile, I copy it to the backup directory before replacing it with a symlink to the dotfiles repo. There might be some magic environment variables or PATH setup that is unique to that particular system's default dot files, so I can take a quick look at them and see if I might need to extend my generic dot files, or maybe add something to the ~/.bashrc.local file, or some such. - Ted

Negative.. but i have sort of this for root accounts, less any fancy make(1) mechanism, however, but there is ~/sic/root.git, and locally i merge/bundle according branches into machine specific branche(s) that can then be pushed/fetched. (My spare "wales" even simply selectively shares the filesystem via snapshots, it is just which /root/.git branch is checked out, and one "/root/bin/backup.sh restore" after FS synchronization; same shared static kernel, but different ssh keys and /etc/hosts, hostname via kernel command line, thanks to /dev/mapper even /etc/fstab is identical. I can git merge "kent" into "wales", and git just does it right!) I "only have symlinks" in my non-root ~/, but i have to create them manually. I do not have many accounts i work with: practically all VMs for building+testing software, so not much effort getting cosy there. Here on "kent" i created them on April 13th 2019, only added .irssi on April 22nd once i started using IRC, too. That is manageable. And all the directories that then exist nonetheless, ~/sic, ~/{,sec.}arena, ~/$USR (~/usr-kent-crux-linux-x86_64/{bin,lib..} here) are created by ~/.profile when i login the first time with the symlink tree present. (But of course they are empty, hm.) It all _is_ in a sec.arena/configs.git directory, but there is home/ as well as .home/ and some others, and only home/ content is to be distributed, so i go into that home and scp(1). The data in there is pretty stable, and what changes sometimes, for example my mailer's config when its development continues, or the .cwmrc just got a "pkill -CONT tmux" last week (^Z delivery sometimes hits tmux not the terminal within where it is typed), is needed only locally. But your approach is much nicer. Just to add that ~/sic is an encfs mount of ~/.sic, ~/.mozilla of ~/.secweb-mozilla (normal browsing container mounts a specific /home partition), and ~/sec.arena of ~/.sec.arena, only the latter two of which are permanently mounted when the lid is up.
