schroot: mount: exec mount_nullfs not found: No such file or directory
Hi BSD Porters, Since last December, I'm unable to use sbuild/schroot on an unstable box : ~# sbuild-update -ugdc unstable E: 10mount: mount: exec mount_nullfs not found: No such file or directory E: unstable-kfreebsd-amd64-sbuild-1329077042-35644: Chroot setup failed: stage=setup-start Chroot setup failed Error setting up unstable chroot Chroot setup failed at /usr/bin/sbuild-update line 166. FTR: 1) I can manually mount -t nullfs via sudo 2) I haven't made any change to PATH 3) AFAIK, mount can't find its helper in /sbin/ This issue is tracked as #650978. Does anybody have a clue ?

Well, I have a suspicion of the problem. 1) schroot setup scripts are run without a PATH being set. This has not been an issue to date for some reason; either this works on Linux and not BSD, or we were hitherto only using shell builtins or commands which didn't rely on PATH. This fix is fairly simple: we need to explicity set PATH in the environment before execing the setup scripts. 2) BSD mount is not using a sensible PATH to search for its helpers. If it's using the user PATH to search for its helpers, there might be security implication here, especially if it's SUID like on Linux. We can fix (1) in schroot fairly simply. (2) might need some investigation by the BSD porters. Regards, Roger -- .''`.

Hi, I tested that /lib/freebsd/mount (for which /bin/mount is wrapper script) does accept a user-specified PATH when looking for a helper to execute.

If anyone allows the use of sudo for /bin/mount, that should reset the environment to something sane, so they should not be at risk.
