The problem is that the above command is not quoted enough for the shell. Bash strips off your " around the context, before the ARGV get to mount. So mount sees an ambiguous option string. Double quoting works succesfully: mount -t tmpfs none /tmp/foo -o 'context="system_u:object_r:tmp_t:s0:c127,c456"' This needs to be documented in the mount(8) man page for 'context', since it is very non-obvious what's going wrong. Fixed by upstream commit 3142564b244b3163446d59f83390f73cea85097b.
