sys-libs/glibc: guard against rendering system unusable, bug #627338 |
| 9 |
|
| 10 |
For cases like FEATURES=config-protect-if-modified |
| 11 |
or custom /etc/nsswitch.conf with only 'compat' resolver |
| 12 |
and external providers glibc upgrade will break local |
| 13 |
user resolution when switching from older glibc. |
| 14 |
|
| 15 |
Bad /etc/nsswitch.conf: |
| 16 |
passwd: compat |
| 17 |
shadow: compat |
| 18 |
group: compat |
| 19 |
|
| 20 |
Good /etc/nsswitch.conf: |
| 21 |
passwd: files |
| 22 |
shadow: files |
| 23 |
group: files |
| 24 |
|
| 25 |
Ok /etc/nsswitch.conf: |
| 26 |
passwd: compat files |
| 27 |
shadow: compat files |
| 28 |
group: compat files |
