+cat << EOF
+Dracut builds a bootable initramfs. The initramfs responsible for mounting
+the root filesystem and starting the main init system.
+
+Many Linux distributions ship a single, generic kernel image that is intended
+to boot as wide a variety of hardware as possible. The device drivers for
+this generic kernel image are included as loadable modules, as it is not
+possible to statically compile them all into the one kernel without making it
+too large to boot from computers with limited memory or from lower-capacity
+media like floppy disks.
+
+This then raises the problem of detecting and loading the modules necessary
+to mount the root file system at boot time (or, for that matter, deducing
+where or what the root file system is).
+
+To further complicate matters, the root file system may be on a software RAID
+volume, LVM, NFS (on diskless workstations), or on an encrypted partition. 
All
+of these require special preparations to mount.
+
+Another complication is kernel support for hibernation, which suspends
+the computer to disk by dumping an image of the entire system to a swap
+partition or a regular file, then powering off. On next boot, this image
+has to be made accessible before it can be loaded back into memory.
+
+To avoid having to hardcode handling for so many special cases into the 
kernel,
+an initial boot stage with a temporary root file system -now dubbed early
+user space- is used. This root file system would contain user-space helpers
+that would do the hardware detection, module loading and device discovery
+necessary to get the real root file system mounted.

+Subject: [PATCH] Wrap __GLIBC_PREREQ usage with __GLIBC__
+
+Fixes build against musl 1.2.2+; earlier versions don't implement it but
+there's no way to know it's presence other than an autoconf-style test.
