[OpenWrt-Devel] Do we really need 000-keep_initrafs_the_default.patch?

[Alexey Brodkin]

Hello,

I'm wondering why there's a need for "000-keep_initrafs_the_default.patch"?
It could be found here:
---------------------->8--------------------
target/linux/generic/patches-3.18/000-keep_initrafs_the_default.patch
target/linux/generic/patches-4.1/000-keep_initrafs_the_default.patch
target/linux/generic/patches-4.4/000-keep_initrafs_the_default.patch
---------------------->8--------------------

With that patch in place for initramfs no additional options are reported
for "/" partition. What's really important is missing info about sizes.
Which in its turn makes opkg think that there's no space on "/" partition
to install software.

I understand that's a sort of corner-case, people rarely install packages on
ramfs but anyways why not?

Just in case that's what I see with the patch:
---------------------->8--------------------
root at lede:/# cat /proc/mounts
rootfs / rootfs rw 0 0
proc /proc proc rw,nosuid,nodev,noexec,noatime 0 0
sysfs /sys sysfs rw,nosuid,nodev,noexec,noatime 0 0
tmpfs /tmp tmpfs rw,nosuid,nodev,noatime 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,size=512k,mode=755 0 0
devpts /dev/pts devpts rw,nosuid,noexec,relatime,mode=600 0 0
debugfs /sys/kernel/debug debugfs rw,noatime 0 0
---------------------->8--------------------

And without:
---------------------->8--------------------
root at lede:/# cat /proc/mounts
rootfs / rootfs rw,size=256168k,nr_inodes=32021 0 0
proc /proc proc rw,nosuid,nodev,noexec,noatime 0 0
sysfs /sys sysfs rw,nosuid,nodev,noexec,noatime 0 0
tmpfs /tmp tmpfs rw,nosuid,nodev,noatime 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,size=512k,mode=755 0 0
devpts /dev/pts devpts rw,nosuid,noexec,relatime,mode=600 0 0
debugfs /sys/kernel/debug debugfs rw,noatime 0 0
---------------------->8--------------------

Note how different is entry for rootfs.

If there're no objections I'll go ahead and send a patch that
gets rid of all 3 patches mentioned above.
