Summary: BusyBox 1.8.2 fdisk doesn't read from stdin
Description:
busybox is used for unattended Linux installations.
During the installation hard drive is partitioned by means of fdisk.
fdisk is used in a batch mode.
This means text file with fdisk commands is prepared -
see attached fdisk-commands file
(partition size values are variable, fdisk-commands is used to create 3
partitions -boot root and swap).
And then fdisk-commands file is passed to fdisk through the stdin.
Somthing like
fdisk /dev/hda < fdisk-commands
In all busybox till 1.7.3 this works fine
But in busybox 1.8.0-1.8.2 fdisk doesn't read commands from stdin.

Just built busybox 1.8.2 and tested it:
# echo q >Q
# strace -o fdisk.log ./busybox fdisk /dev/sda1 <Q
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF
disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that the previous content
won't be recoverable.
Warning: invalid flag 0x00,0x00 of partition table 4 will be corrected by
w(rite)
Command (m for help): q
#
strace log clearly shows that it did read from stdin:
write(1, "Command (m for help): ", 22) = 22
read(0, "q", 1) = 1
write(1, "q", 1) = 1
read(0, "\n", 1) = 1
write(1, "\n", 1) = 1
Please provide more details (your .config, and strace log of fdisk
invocation which doesn't work for you)
