Bug#736519: aufs: nfsroot+aufs gives selective permission(-s) problem
Package: src:linux
Version: 3.2.51-1
Severity: normal
File: aufs
Dear Maintainer, I have a small issue of using aufs module.
I use readonly NFSROOT with tmpfs overlay for diskless workstations.
Issue I faced with is that users (whose supplementary groups list contains 'fuse') can't exec /bin/fusermount (permission denied).
And the second issue - file is not found by which command.
Both of them disappear if file is being touch-ed.
Attachments contain are obtained usin following commands:
a.dunaev $ strace -o which-trace.pre.txt which fusermount
a.dunaev $ sudo touch /bin/fusermount
a.dunaev $ strace -o which-trace.post.txt which fusermount
I've using customized initramfs. Specifically I've added nfs-bottom script (see attachment).
