NAME¶

seunshare - Run cmd with alternate homedir, tmpdir and/or SELinux context

SYNOPSIS¶

seunshare [ -v ] [ -C ] [ -k ] [ -t tmpdir ] [ -h homedir ] [ -Z context ] -- executable [args]

DESCRIPTION¶

Run the executable within the specified context, using custom home directory and /tmp directory. The seunshare command unshares from the default namespace, then mounts the specified homedir and tmpdir over the default homedir and /tmp. Finally it tells the kernel to execute the application under the specified SELinux context.

-h homedir

Alternate homedir to be used by the application. Homedir must be owned by the user

-t tmpdir

Use alternate temporary directory to mount on /tmp. tmpdir must be owned by the user

-r runuserdir

Use alternate temporary directory to mount on XDG_RUNTIME_DIR (/run/user/$UID). runuserdir must be owned by the user

-C --capabilities

Allow apps executed within the namespace to use capabilities. Default is no capabilities

-k --kill

Kill all processes with matching MCS level

-Z context

Use alternate SELinux context while running the executable

-v

Verbose output

EXAMPLE¶

Run bash with temporary /home and /tmp directory
# USERHOMEDIR=`mktemp -d /tmp/home.XXXXXX`; USERTEMPDIR=`mktemp -d /tmp/temp.XXXXXX`
# seunshare -v -h ${USERHOMEDIR} -t ${USERTEMPDIR} -- /bin/bash
