We have NetBSD 1.5.2 running on an embedded system with a RAM disk. We
gzip the ramdisk in flash then gunzip it to ram. The issue is that the
embedded system needs to get to a state quickly to service interrupts
etc. and the gunzip is a lengthy process. We want to move the gunzip to
the point after all the devices are initialized and interrupts are
enabled. I have tried moving it but I get the prompts asking where to
mount things. The file systems are started early in main
(init_main.c), but they appear not to be used till start_init
(init_main.c).
Is it possible to move all the file system startup code to a point after
the device drivers are setup and interrupts enabled, or would this break
a fundamental operating assumption for NetBSD?
Thx,
kyle
