catalyst/targets/generic_stage_target.py: mount /dev/shm on linux |
| 9 |
|
| 10 |
Add shm targets defaults. Anthony G. Basile <blueness <AT> gentoo.org> |
| 11 |
Some build systems require /dev/shm to be mounted, like python's |
| 12 |
build system. We make sure that on Linux systems, /dev/shm is |
| 13 |
mounted in the stage chroots. See bug #496328. |
| 14 |

Douglas Freed <dwfreed <AT> mtu.edu> : |
| 16 |
Mount /dev/shm in the chroot with the right options |
| 17 |
Bind mounting /dev/shm into the chroot isn't a good idea, as there may |
| 18 |
be collisions and result in weird side effects. Instead, we can just |
| 19 |
mount a new tmpfs there, with the right options to ensure security. |
