3 ### cached kernel parameters :
4 #
5 # modprobe=
6 # list of modules to load, example modprobe=r8169,btrfs
7 #
8 ### Frugal mode or live CD : using a root ram disk.
9 #
10 # tmpram= [RAMDISK]
11 # minimum % of free RAM to build the root tmpfs, default 100
12 # a lower value may work, such as 50
13 # rootfssize= [RAMDISK]
14 # size of / regarding the RAM size, default 90%
15 # rootfsinodes= [RAMDISK]
16 # files count of / regarding the RAM size, default 0 (unlimited)
17 #
18 ### Indirect mode ; an initramfs is used to mount root from the hard disk.
19 ### Any rootfs should fit, minimum required is slitaz-base.
20 #
21 # mount= [MOUNT]
22 # device with root loop file or sub directory
23 # posixovl [MOUNT]
24 # use posix attributes on a non posix filesystem (VFAT, NTFS...)
25 # loopfs= [MOUNT]
26 # loop file for root filesystem
27 # subroot= [MOUNT]
28 # sub directory for root filesystem
29 # bindfs= [MOUNT] (deprecated)
30 # bind out of root tree part
31 #
32 ### Special disk mode ; needs extra modules/softwares from preinit flavor.
33 #
34 # dmraid= [RAID]
35 # root semi hardware raid device name in /dev/mapper
36 # softraid= [RAID]
37 # root software device name in /dev/mapper
38 # lvmroot= [LVM]
39 # root logical volume name in /dev/mapper
40 # cryptoroot= [CRYPTO]
41 # encrypted root device using luks or loop-aes
42 #
43 ### Special mode used by loram flavor with aufs/overlayfs & squashfs
44 ### incremental/nested rootfs (russian dolls).
45 #
46 # rodev= [LORAM][MERGE]
47 # device (+ optional path) for the read only aufs branch
48 # rwdev= [LORAM][MERGE]
49 # (persistent) device for the r/w aufs branch instead of the ramfs
50 # isofs [LORAM]
51 # do not use squashfs filesystem images, but the cdrom filesystem only
