Where is the initramfs archive in the Linux kernel?
The old initrd was always a separate file, while the initramfs archive is linked into the linux kernel image. (The directory linux-*/usr is devoted to generating this archive during the build.)
Do you need initramfs before mounting rootfs?
In other cases where the kernel is e.g. on a /boot partition, the initramfs on the same partition can be accessed directly before mounting the rootfs as others have stated. In some cases the initramfs can be built into the same file as the kernel but this is not always the case.
Why do I need initramfs in LFS environment?
There are only four primary reasons to have an initramfs in the LFS environment: loading the rootfs from a network, loading it from an LVM logical volume, having an encrypted rootfs where a password is required, or for the convenience of specifying the rootfs as a LABEL or UUID.
What’s the purpose of the initramfs file system?
The only purpose of an initramfs is to mount the root filesystem. The initramfs is a complete set of directories that you would find on a normal root filesystem. It is bundled into a single cpio archive and compressed with one of several compression algorithms.
How to show the parameters of an archive?
The SHOW PARAMETER command shows us exactly what has been entered in the init.ora parameter file and equates to the actual parameter names if we stick to using the LOG_ARCHIVE_DEST_n parameters.
Do you need to use Archive Log List?
While the ARCHIVE LOG LIST command gives us a quick overview of archive status, it clearly should not be used to report on destinations.
Where do I find my archive on my computer?
The V$ARCHIVE_DEST view gives us a clear view into where on disk these destinations are and , when using the LOG_ARCHIVE_DEST_n parameters, closely relates to what was entered in the init.ora parameter file (minus the LOCATION clause).
