Sorry for bumping the old thread.
So does that mean say i repeatedly generate seeds say 100 seeds one after the other before finally deciding the choose the seed for my wallet. Does that make the seed less secure?
no it doesn't. /dev/urandom can generate unlimited cryptographically secure random numbers. it doesn't run out.
It doesn't run out that's true.
But there's something weird definitely.
I tried it. I created seeds in electrum wizard. After 30,40 seeds the wallet closed. (may be randomness was weakening? ) . I again open and tried. Same happened again.
Also the post i quoted. Electrum developer also confirmed /dev/urandom can run out of entropy if it is called repeatedly.
Found similar concern here as well -

https://bitcoin.stackexchange.com/a/62894/5273also this answer to the stackoverflow question is the correct one:
https://stackoverflow.com/a/5498100/dev/urandom only needs to be seeded with a small amount of entropy. this happens at bootup. after that it's pseudo random number generator can generator unlimited amount of random numbers.
