Subject: [PATCH] kdumpctl: check and generate /etc/vconsole.conf
|
|
|
|
For VMs created from KVM Guest images, /etc/vconsole.conf is missing
|
|
so that dracut module 10i18n will install all kbd files.
|
|
|
|
```
|
|
# du -sh initramfs/squash/usr/lib/kbd/*
|
|
438K initramfs/squash/usr/lib/kbd/consolefonts
|
|
340K initramfs/squash/usr/lib/kbd/consoletrans
|
|
2.1M initramfs/squash/usr/lib/kbd/keymaps
|
|
232K initramfs/squash/usr/lib/kbd/unimaps
|
|
```
|
|
|
|
From man 5 vconsole.conf, KEYMAP= defaults to "us" if not set. We can
|
|
safely generate a /etc/vconsole.conf with KEYMAP=us by localectl to
|
|
reduce the initramfs size.
|
|
|
|
```
|
|
# du -sh initramfs/squash/usr/lib/kbd/*
|
|
11K initramfs/squash/usr/lib/kbd/consolefonts
|
|
121K initramfs/squash/usr/lib/kbd/keymaps
|
|
```
