mkinitfs - Generate an initramfs
mkinitfs [OPTIONS] [KERNELVERSION]
mkinitfs
collects files from the root file system and creates a
compressed initramfs from it.
−b BASEDIR
Dont use files from the root file system, use specified path instead.
−c CONFIGFILE
Use configfile instead of /etc/mkinitfs/mkinitfs.conf.
−C ALGORITHM
Compress initramfs using gzip (default), xz, zstd, lz4 or none.
−f FSTAB
Use fstab instead of /usr/share/mkinitfs/fstab.
−F FEATURES
Use specified features.
|
−h |
Print this help. |
−i INITFILE
Use initfile as init instead of /usr/share/mkinitfs/initramfs-init.
|
−k |
Do not clean up temporary files. |
|||
|
−K |
Also copy host apk keys to initramfs. |
|||
|
−l |
Do a dry run and only list files that would have been used. |
|||
|
−L |
List all available features. |
|||
|
−n |
Don’t include kernel modules or firmware into the initramfs. |
−o OUTFILE
Set another outfile.
−P FEATURESDIR
Prepend features.d search path. Use this if you want to define your own features outside of the system-wide directories.
|
−q |
Quiet mode. |
|||
|
−s |
Include modloop signature. |
−t TMPDIR
Use tempdir when creating initramfs image.
/etc/mkinitfs/mkinitfs.conf
Default configuration file. It contains the list of default features in the format of features="...".
/etc/mkinitfs/features.d/FEATURE.modules
Contains a list of kernel modules. Using the feature will cause the given kernel modules to be included in the initramfs. The modules are given by their filesystem paths, relative to /lib/modules/KERNELVERSION/.
/etc/mkinitfs/features.d/FEATURE.files
Contains a list of absolute file names which will be included into the generated initramfs if the feature is enabled.
/usr/share/mkinitfs/initramfs-init
Shell script which will be placed as /init in the initramfs. This functions as the first executed program in early userspace.
