boot from ram ramdisk ? generic newb question
Questions first incase no details necessary and u wana skip'm
Are no partitions mounted? so its safe to modify/partition/test/etc the HDD with tools running from the ramdisk (which ofcourse normally warn to make sure the HDD is unmounted and not in use before proceeding)
If answer to ?1 is, Yes (no partitions are actually in use) and safe to modify with utilites running from a ramdisk. Not mission critical but would be nice if anyone knows how to boot SystemRescueCD from ramdisk ? bellow is example of my normal grub legacy stanza i have used for it.
Im using slitaz as the example but my question is for any distro when booting from ramdisk.
I booted a slitaz cooking distro the same way ubuntu instructs to boot there ISO from HDD. gurb legacy slitaz stanza ex bellow.
slitaz started up ok afk ,and shows no HDD partitions mounted ? however i have no clue if its Actually true or not. I am NOT a linux guru, i only know the basics and a few specific tasks for my needs.
I know slitaz is designed to boot from ram, but its also not stated anywere on there site how to boot in this fashion, instead the usual CD/USB/or HDD etc install methods. So i dont know if this is normal behavior for slitaz as in doesn't mount partitions even if installed on HDD? or even if theres issues or not with the way i booted it and its a error/not displaying things correctly etc? It boots for me though basic operations iv used it for seem to work fine? im already aware its non-persistent in this way, which i actually prefer atm.
