Subject: [PATCH 31/31] fix(dracut-functions): avoid awk in get_maj_min()
|
|
|
|
The `get_maj_min()` cache lookup is commonly used
|
|
across many flows. While `awk` should be available,
|
|
some highly constrained environments may not have it.
|
|
A second call to `grep` can provide the same behaviour
|
|
without adding a dependnecy.
|
|
|
|
Lines in the cache will be of the form "/dev/sda2 8:2".
|
|
`awk '{print $NF}'` returns the last word of a matching line. Since
|
|
the initial matching regex is so specific a second call to grep can
|
|
easily extract the last word.
|
|
|
|
(cherry picked commit ec7efd5701e9a1b24f2e85666d625fb1fe46ce86)
