Another bit of trivia about the shebang support in Linux is that is possible to build the kernel without it. https://github.com/torvalds/linux/blob/master/fs/Kconfig.bin... config BINFMT_SCRIPT

I don't quite understand what --exec does. If I leave out --exec from example 3, is it supposed to prevent bash from executing other programs? $ landrun --log-level debug --ro /usr/bin,/lib,/lib64 /usr&#x2F

Large projects like the Linux kernel, which are mostly C, use the preprocessor in .S files quite heavily. Linux has hardly any .s files. ~/linux$ find . -name '*.s' ./arch/x86/kernel/asm-offsets.s

Function typedefs make this less confusing by removing awkward parentheses. e.g. typedef int read_block_fn(void *context, u8 *buf, unsigned int block, size_t len); https://github.com/torvalds/linux/blob&#x2F

Yes, these commands have way too many options for anyone to remember. The commands are best wrapped up in a script. An ISO install is usually a manual process that can take time, but it is definitely easier.

Shebang scripts are supported directly by the kernel via the exec family of system calls, so ld.so shouldn't be involved. https://github.com/torvalds/linux/blob/master/fs/Kconfig.bin... con
