[Bug 994539] Re: resolvconf 1.63ubuntu12 failed to install/upgrade -- "lsattr: Inappropriate ioctl for device While reading flags on /etc/resolv.conf"

[Stéphane Graber]

Are you using reiserfs by any chance? or any non-ext filesystem?

root at castiana:~/Desktop/test/mnt# ls
root at castiana:~/Desktop/test/mnt# touch bla
root at castiana:~/Desktop/test/mnt# lsattr bla
lsattr: Inappropriate ioctl for device While reading flags on bla
root at castiana:~/Desktop/test/mnt# grep reiserfs /proc/mounts 
/dev/loop0 /home/stgraber/Desktop/test/mnt reiserfs rw,relatime 0 0
root at castiana:~/Desktop/test/mnt# ls
bla
root at castiana:~/Desktop/test/mnt# lsattr bla
lsattr: Inappropriate ioctl for device While reading flags on bla
root at castiana:~/Desktop/test/mnt# echo $?
1


>From their manpage lsattr/chattr are designed for ext filesystems, there isn't any guarantee that they'll work on something else.

Based on that, it should be safe to ignore that specific error as chattr
wouldn't have worked on such a system either and so resolv.conf can't
possibly be immutable.
