#utillinux — Public Fediverse posts

It's interesting to note that #Debian simply gave up on util-linux ever doing this right, and patched it all out; having a PAM module do the work instead. Just as #FreeBSD arranges login database updates.

#utillinux #login

One of these days, I hope, util-linux's login program will clean up its own utmp entries.

#systemd's utmp support is optional, and on systems built without it nothing cleans up the USER_PROCESS entries that login adds.

But util-linux's login is a forking login anyway, because it uses PAM. It can just clean up after itself in the parent process that added the record in the first place.

#TIL about the `namei` tool which is sort of like #traceroute but for filesystem traversal.

This is especially useful on #nixos where you're frequently dealing with stuff that is multiple levels of symlinks deep.

It's probably already on your system because it's part of #utillinux; go try it out:

namei `which ls`

#namei #symlink #linux
