.Dd April 18, 2014 .Os Void Linux .Dt xbps-uchroot 8 .Sh NAME .Nm xbps-uchroot .Nd XBPS utility to chroot and bind mount with linux namespaces .Sh SYNOPSYS .Nm xbps-uchroot .Op OPTIONS .Ar CHROOTDIR .Ar COMMAND .Op ARGS .Sh DESCRIPTION The .Nm utility allows users to chroot and bind mount required pseudo-filesystems (/dev, /proc and /sys) in the target .Ar CHROOTDIR to execute .Ar COMMAND . The .Nm utility uses by default Linux namespaces to isolate IPC, PIDs and mounts to the calling process. If running in a OpenVZ container, these namespace features are simply disabled. .Sh OPTIONS .Bl -tag -width -x .It Fl D Ar dir Specifies a full path to a directory that will be bind mounted at .Ar CHROOTDIR/xbps-packages . .It Fl H Ar dir Specifies a full path to a directory that will be bind mounted at .Ar CHROOTDIR/host . .It Fl S Ar dir Specifies a full path to a directory to allow shm functionality to be used in the target .Ar CHROOTDIR/dir . If your system uses .Sy /dev/shm use it, otherwise use .Sy /run/shm . .Sh SECURITY The .Nm executable must be setgid to function properly and shall only be executable by a specific group to avoid security issues (4750). .Sh NOTES The .Nm utility uses Linux specific features (namespaces) and it's not meant to be portable to other Operating Systems. .Sh SEE ALSO .Xr xbps-checkvers 8 , .Xr xbps-create 8 , .Xr xbps-dgraph 8 , .Xr xbps-install 8 , .Xr xbps-pkgdb 8 , .Xr xbps-query 8 , .Xr xbps-reconfigure 8 , .Xr xbps-rindex 8 .Sh AUTHORS .An Juan Romero Pardines .Sh BUGS Probably, but I try to make this not happen.
