Also to mention, the installation following adjustment of the USE flags |
| 35 |
completes like so: |
| 36 |
============================================ |
| 37 |
* Messages for package sys-fs/lvm2-2.02.184-r4: |
| 38 |
|
| 39 |
* Make sure the "lvm" init script is in the runlevels: |
| 40 |
* # rc-update add lvm boot |
| 41 |
* |
| 42 |
* Make sure to enable lvmetad in /etc/lvm/lvm.conf if you want |
| 43 |
* to enable lvm autoactivation and metadata caching. |

========================== |

|
| 47 |
There is no lvm init script left in my system: |
| 48 |
|
| 49 |
# rc-update -s -v | grep -i lvm |
| 50 |
# |
