You are using testing/unstable, aren’t you?
The su binary was replaced with another one, and now Debian is
breaking user space again. :-(
Now su alone doesn’t change the path but keeps the user path. You have
to use „su -”.
The util-linux implementation of /bin/su is now used, replacing the
one previously supplied by src:shadow (shipped in login package), and
bringing Debian in line with other modern distributions. The two
implementations are very similar but have some minor differences (and
there might be more that was not yet noticed ofcourse), e.g.
- new 'su' (with no args, i.e. when preserving the environment) also
preserves PATH and IFS, while old su would always reset PATH and IFS
even in 'preserve environment' mode.
- su '' (empty user string) used to give root, but now returns an
- previously su only had one pam config, but now 'su -' is configured
separately in /etc/pam.d/su-l
The first difference is probably the most user visible one. Doing
plain 'su' is a really bad idea for many reasons, so using 'su -' is
strongly recommended to always get a newly set up environment similar
to a normal login. If you want to restore behaviour more similar to
the previous one you can add 'ALWAYS_SET_PATH yes' in /etc/login.defs.
Shade and sweet water!
so where is user's path kept these days as it seems I might have set
user PATH to root PATH ?
and I should probably put it back as it was.
