Subject: [PATCH] v2v: Increase Linux minimum root filesystem to 100 MB
|
|
|
62f9b7 |
|
|
|
62f9b7 |
Ming Xie created a RHEL 8.3 guest which required around 70 MB free in
|
|
|
62f9b7 |
order to recreate the initramfs (temporary space used by the pigz
|
|
|
62f9b7 |
step). Increase the minimum space required to 100 MB, the same as for
|
|
|
62f9b7 |
Windows.
