* umount: add note about namespaces too --all-targetsKarel Zak2013-02-272-6/+6
| | | | Signed-off-by: Karel Zak <kzak@redhat.com>
* umount: add --all-targetsKarel Zak2013-02-262-59/+136
| | | | | | | | | | | | | | | | | | | | | The same source (whole filesystem or filesystems subvolume) could be mounted on more targets (mountpoints). For example bind mounts or btrfs sub-volumes. If you want to detach the source device from the system then you need to unmount all the mountpoints. umount --all-targets <device|mountpoint> provides this functionality. This option could be used together with --recursive. Then all nested mountpoints within the filesystem are unmounted too. For example: umount --recursive --all-targets /dev/sdb1 should be a way how to make the device unmounted at all. Signed-off-by: Karel Zak <kzak@redhat.com>

* unshare,nsenter: spawn shell by defaultZbigniew Jędrzejewski-Szmek2013-02-144-15/+19
| | | | | | | | | | | | | The behaviour mimics chroot. Possibly it would have been nicer to to query the password database in the new namepace and run the shell of the user there, but it's hard to do correctly. getpwuid() might need to load nss plugins, and the arch in the new namespace might be different (in case of NEWNS mounts), or the hostname might be different, etc. So in general it's not possible to do it reliably.

* libmount: correctly propagate ambivalent blkid probing resultsKarel Zak2013-02-131-0/+5

* docs: align nsenter.1 man page with howto-man-page.txtSami Kerola2013-01-251-75/+126
| | | | | | | | | | | | | | Most visible change; the --target option has a path - explanation table instead a long paragraph. This makes pairing of the information easier for an average user such as me. The rest of the changes are about aligning with howto, i.e., fix spaces after dots, URL & mail address macros, remove inline emphasis where possible, mark directory paths and words with underscore to be line breakable, use optional option syntax from howto, cut line lenght to 80 chars.

* nsenter: adjust few error messagesSami Kerola2013-01-251-6/+6
| | | | | | | | | | | | | | The 'neither filename nor target' is changed to use errx() rather than err(), because the errno is indicating success at the time of fatal error which is wrong message for an user. The "cannot open %s" is same string as in other files, making translators to work less. Remaining changes aim to ease understanding what went wrong for a non-programmer audience.

* unshare,nsenter: Move the old libc handling into a common header namespace.hEric W. Biederman2013-01-172-55/+2Star
| | | | | | | | | | | | | | Move the defitions of CLONE_NEWNS, CLONE_NEWUTS, CLONE_NEWIPC, CLONE_NEWNET, CLONE_NEWUSER, CLONE_NEWPID into namespace.h in case sched.h does not provide those definitions. Are there systems around that are old enough that still need this? Move the definitions of unshare() and setns() into namespace.h for supporting old versions of libc that does not provice these. I have tested this support with setns as I still have systems old enough that glibc does not wrap setns. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
